Awesome spine whack!!!!!
That was for Nero
More solid testing. The 0470 is a solid design. I've tested several ZT models with a palm wack and seen no issue with lock stability. Thanks for another great video.
I think Pete just leveled up, clean shaven and professional coif...is this the final form?
Must be up to something...
I camp and hike with my ZT's and have never experience a lock failure. All these people fretting over that are so funny lol
far out i forgot about magic eye images. the knife lab intros are 100% my new favorite thing
Thanks for all the work you have done testing and putting together videos fun to watch. Again thanks 🐱
I lobe The Knife Lab intro so much! Especially the robots 🤖
What a difference, that's a lot of edc . I personally put a 17° edge on a few different knives with different steels and I just keep rolling the edge at about 30 percent of the steels cutting ability with a 20° edge. Iam a Carpenter by trade , and usually cut stuff like plastic , wood, thick cardboard , plastic ties , insulation , ect. So , I just keep a polished
20° edge and its fine , no rolls , no problems , so I understand ZT's thinking with its thicker edges . That said , yours was definitely the thickest edge that I've seen on a ZT. Just my 2 cents .....
A ZT I want for sure. Great job getting it to perform better
Thanks for doing this. I had somewhat given up on ZT after their lackluster cutting performance. I´m glad that their CPM 20CV knives perform on par with other manufacturers. My only ZT is a 0562CF (in 20CV,) so this bodes well.
Just watching this. Great video! I was excited when this knife released because I love the Atmos, but I was disappointed to find it wasn't also a hollow grind. I love having an EDC razor and this looks like a great solution!
you can request a deep carry clip from Kai.USA (from the ZT560, which shares the same screw pattern) which they will happily send you free of charge (I have done this for both my ZT 0456 and 0470), also while you are at it request more screws to fill up the empty screw holes (again I have done this for all of my ZT's that I own), and again they will send them to you free.
I have to say I really like the ZT0470 and appreciate the fact ZT is going down this path of more EDC'able sized knives.
Nice music choice for the second rope cut!
This knife sees more time in my pocket than any other right now. I picked up one that was anodized blue from USA Made Blade, and love it!
I have an 0562cf that held up to spine whacks fine, until app. 2 months after carry. It seems like there is enough slack in the lock up to allow a bounce of the tang on the insert. Hopefully your zt holds up fine. Thanks for the video Pete!
Thank you for this video. I think I will try this out on my benchmade 940...
The knife lab intros are the best thing ever. Those robots on stripper poles🤣🤣🤣. Another great vid Pete keep it up
So true! I think the AD-10 intro was one of his best.
I recognize the 2nd cut test song, but I cannot identify the 1st and it is driving me INSANE lol. Excellent video Pete, now you have me thinking about my 0562, I have never sharpened it. Perhaps I should make a vid checking out the durability.
I would imagine that reprofiling to a shallower angle allows it to hold the sharp edge longer due to needing less pressure to cut through the rope.
Love me some laaaaiiiid back geometry😍
I love your videos!!
Sinkevich is by far my favorite knife designer.
Awesomeness 😎
Not only do you review knives and stuff, but you get an awesome workout too! Soon you'll look like that Charger zombie from Left 4 Dead 2. Nice work.
Pete that kind of guy to close the kitchen draws with his hips.
So I’ve been using a kme for a few years with the diamond stones to 1500. I would then go to the films up to 4000ish. I then got a kangaroo strop and the diamond emulsion,and it is next level sharp. Give her a go. It’s the shit.
I just got a brand new 0562 and it locked up fine too
Take it to the limit super knive steel.very nice .
Hair cut!
...what knife would be best for that I wonder?
best opening
Also I'm pretty sure 20cv and M390 are the exact same other than the method of production (3rd generation powdered vs CPM)
At least that's what I thought....
Lol the lock held up! Try it again in a few months after the spring tension has relaxed a little bit. It seems to be degenerative in my experience.
Same, all my ZTs have been good for the first few weeks and then all of them have vertical flex/play and lock failure after that.
Bullshit. I've used a 909 like I hate it for over a year. Lock hasn't even moved nor has any play ever developed in any direction.
pete, you are a glutton for punisment but we appreciate it/ What a difference a few degrees make/ thsnks Harry
I'd be curious to see how it performs with a mirror edge, and toothy edge
Nice instructional vid.
Which KME hones/stones did you use to re-profile the 20CV blade? Just the 1500 grit?
140/300/600/1500
Use it for a bit the lock will stop working my zt 0562 was fine before I got rid of it it was a slipjoint
It's now well known fact that the edge is not the problem.. Heat Treatment is the problem across entire ZT line.. 20cv by ZT was tested by "in the pocket" at ridiculous 57-58hrc witch is between 3-5hrc points down.. Indeed "Drop that Zero and give it to Spyderco"
In the lab? I just got mine at Gander Outdoors half off!
Worksharp 20 dps test next?
I may have missed it but what angle did you sharpen it to? 15? Ill do the same with mine👍🏻
I wonder how much of the difference is angle vs burnt edge
Probably not much. This result is 100% consistent with every other test I've seen.
I'm sure I'm not the first person to ask this but...what do you do with all that rope after cutting it up? Just put it in the trash like a normal purpose, or have you found some other use for it?
What do you do with all the cut rope?? Can always ship it to me in bulk if you have no use for it! ha
All guys prefer a narrow "V".
Wow and that knifes worth 240$ wat a poc
Hi Pete, great vid! I have grip 551 in 20cv, what angle you recommend, to put on this knife ? Polish or toothy ?
With regard to finish, I don’t know yet to be honest, which is ideal for this steel. Angle wise Its definitely tough enough to take 17° at least.
@@CedricAda Thank you for fast answer. I will try in future that angle but now im on the stock edge angle :-) Btw im restoring pretty beaten up delica 4 in vg10. I will stone wash the blade and put new edge. You said, that 12degree per side is very good for vg 10, right? Best regards from Poland!
You are oppressed by the number of followers and comments I wish you progress and success because you deserve it
You keep your onions in the refrigerator?
I apologise for the off-topic comment, but could you please review a Manly knife? They are reasonably priced, have thin grinds, and seem to be made of good steel. Thank you.
Just got my 0470 and went to loosen the pivot for disassembly. And boom the D shape "stationary pivot" rounded out due to the tons of loctite on the pivot. Now I have to spend my money to send it out to ZT for god knows how long just to be able to disassemble my $240 knife. This should not be the case and I'm sure that there going to try and charge me for whatever part they have to replace. It's honestly ridiculous. I love this knife it's so smooth and looks amazing got a MXG deep carry pocket clip and it's perfect except for the fact that I CANT EVEN TIGHTEN/LOOSEN THE PIVOT. I really know understand why ZT wouldn't just put an octagonal shape instead of a D and they put the grove in the CF from what I heard so I really hope they don't try and charge me for a whole new inlay. Fingers crossed they take care of me.
noooo! that sucks! im not a huge fan of the company. I love this knife though and like a couple of their others. Let me know how you go
Cedric & Ada Gear and Outdoors Will do I'm sending it out tomorrow. They claim the turn around time is about 4 weeks but I saw a video from EDC gear reviews where he sent his out and didn't get it back for 4 months. They claimed it was because they have had more knives come back than ever which isn't a good sign. But fingers crossed they don't take forever and try to charge me for something that's clearly on them. Glad yours is in tip top shape.
@@killabee-2384how did it go?
Pete, use the knife for a couple months and test spine wacks again please! All the ZTs ive owned were fine when they were new and developed play/lock failure after a few weeks of even light use. Every single one.
will do - the review will be some time off so i’ll keep checking on it
I ate a whole raw onion once and immediately puked right afterwards
Pizzaxbandit how did you get past the first bite? Lol
@@49giants3 with sheer determination
Pizzaxbandit geez that’s incredible in a way
Dare? Bet?
I love raw onions
I think you've got it wrong. A narrower angle is known to be LESS durable; easier to bend over or chip. I think what really happened here is that the factory edge was quite coarse and toothy. You broke off all the factory "teeth" rather quickly. (whereas Spyderco's factory edge was probably finer, so it lasted longer)
Then, you re-sharpened it and put a VERY fine edge on it, with the strop. Much smaller teeth on the edge. So despite having a narrower bevel, it cut longer.
The thing to do now is to put a wider angle micro-bevel on it, but with a super fine finish, like you did here. That edge should last even longer. You've already put in the work to have a narrower angle main bevel. Now just put the proper micro bevel on it and it will just take a few swipes to re-sharpen.
What do you think?
Side note: consider buying The Razor Edge Book of Sharpening. It's a simple book written by a good ol' American hillbilly. To demonstrate his method, he had his daughters sharpen up a double-bit axe and he then shaved his beard with it. With the knowledge that's in this book, folks probably wouldn't keep buying sharpeners.
Haha, I just imagine some serious knife person stumbling across this channel and seeing you eat a raw onion 😂
He's super serious about it tho
@@valkyriesurvives5109 haha, knife people are a weird bunch 😂
I once juiced an onion. It was terrible...
thechugdude and was that a surprise lol
Pwede ko po ba mahiram yan? Gagamitin lang po namin pang tule sa akin.. Ang talas po kasi eh. Maraming salamat po..
If you're not spine-whacking on a roll of masking tape you're not doing it right.
I'm guessing there's a burnt edge on that knife.
Or heat treatment issue, like with the infamous m390 modus
Supersteel Steve has videos showing that it takes at least 3 sharpenings to fully remove the "burnt" steel. Some knives are more stubborn and can take as many as 5 or even 7.
ZT also usually runs their knives a tiny bit softer. I guess they just don't want to use multiple heat treat protocols for the same steel on different models.
Is it it possible? Sure. But Pete's geometry explanation covers this scenario perfectly. Every time someone tries a more acute (within reason) edge on a retention test like this, the acute angle wins.
@@JacksonKnives man, watch his vids m390 unleashed, this steel can produce much higher performance in number of cuts. Something is wrong with this particular blade
@@don0giorgio The previous 20CV test, Benchmade Grip, got 351 cuts @ 20DPS. This is 375 at 17DPS. In M390, Lionsteel TRE did 334 @ 20 DPS. Tests with the Steel Will polished go higher @ 20DPS, then double at 11.5 DPS on the Tormek.
So... more acute, cuts longer. Is there room for variability in heat treat, burnt edges and Pete's cutting technique? Definitely! But if you look at the CATRA data Larrin published on knifesteelnerds, the relationship between edge angle and slicing performance is very clear.
Pete's explanation is simple, concurrent with what other testers are saying, and borne out by all the data. If Pete wants to take this back to whatever the factory angle is (25 with some convex?) there's a better than amazing probability that the cutting performance would drop again. If he does that and calls out the burnt edge controversy, I'll send him a box of knives in gratitude.
How do you avoid breaking the tip when useing a KME ?
Frank Rice just make sure I dont go over the end ever, stopping about halfway across the stone while I’m doing the back and forth motions. Still very easy to round it off it it accidentally drags over the end
@@CedricAda thanks Pete
Wtf you keep onions in the fridge
Spit or swallow....... the onion ?. What did you do.
o0FranklySpeaking0o down the hatch. that was the only bite though 😂
I’m laughing soo hard... bet Nero was too
I'm like 90% certain that you can just 1:1 swap the Atmos clip onto the 0470
edit: *eat a raw onion* me: nooooo don't do i - shit too late
*comments off camera*
I’m sorry Pete, how could you have strawberry milk in the fridge, choco milk is the superior
I'd get the clip anodised and swap it. I'm a hardcore Lefty. LOL.
It seems to me that all these factory edges are “burnt” a little. When they put the grinder on there to put the factory edge on, it heats up the very surface of the edge, and the apex, and ruins the heat treat, just on the surface, or “burns” the edge. Sharpening with stones will take off that burnt steel, and get down to the fresh steel underneath, and your performance will increase a lot. And then thinning it out seems to help you out as well.
I wish ZT designs like that were thinner behind the edge... good video brother, God bless
Prestonscott536
If uncooled Power abrasives have been used you can bet all of them are burnt; it takes about 3-4 sharpenings to stabilise, in general that is.
That’s about what I saw, 3 or 4 sharpenings, and then those edges start to keep and keep and keep.... just takes time to get into the meat of that blade
Prestonscott536
Yessir, that is what most objective observations show.
That's one way to look at it, but this result is consistent with other similar tests. Acute edges always out-cut obtuse edges, so pick the most acute edge/thinnest blade that's practical for the application. Larrin Thomas has some great analysis on knifesteelnerds.com.
If Pete wants to re-sharpen this edge to the factory angle, we may get a more conclusive answer, but I don't think he's going to do it. XD
You’re doing it wrong! A ‘real’ knife reviewer would [insert idiotic snarky comment here] and you’re [expand on previous idiocy & smarminess].
Good vid as always, Pete! And a damned nice knife.
can I double like this one... mkay thanks
Hey Pete, good one, so its 15 dps now or what?
don0giorgio 17° 😃
I never use factory edges. They always seem weak and my wicked edge is much stronger and sharper
Gloves bro wear some fucking gloves!!!
